The only time during the race was laps 19 to 21.

On lap 19, Trulli was still a few seconds behind.

Lap 20, he closed but was still not sufficiently close by any stretch of the imagination. Lap time 120.3

Lap 21 he closes further but not sufficiently to be impeded. 120:1

Lap 22, he finally closes up on Lewis on the 2nd half of the Lap but I can't tell if he overtakes and pits or sits behind and pits.

I also can't tell about any blue flags.

What is obvious is he was only in a potential situation to overtake for a few corners.

Thanks to vision F1
Please re-watch lap 2 for the that race to see why watching the dots is useless for this kind of argument... Hamilton was spun out and the whole field passed him before he could get moving, but on vision it takes almost the whole lap before the last car in the "main" group gets past Hamilton's dot, so in other words, IF Hamilton was holding up Trulli, you won't see it watching Vision...
